So it looks like there are two bearings on the inside of the wheel, and probably a third against the tire? I wonder how wobbly that gets when the tire pressure drops. I would think that just having a triangle inside the wheel with bearings at each of the points would do the same job without the wheel being pinned along only a quarter of its circumference. Cute bike, anyhow.
